11 will close, due to the equalizing of the pressures in the auxiliaryreservoir and m the brake pipe'2.- If for any reason the valve 6 shouldnot fall the air will 'pass through the conduit 17 from the auxiliaryreservoir to the upper side of the valve 6 and cause it to seat upon thevalve seat 7 thereby closing the passage of air to the valve chamber 5and the air is shut off from the auxiliary reservoir. The springs 10 and15 assist in causing the valves 11 and 6 to close, although they may bedispensed with, but it has been found advisable to use them to insurethe seating of the valves.

A port 22 is formed in the bottom of the main chamber 4 and connected tothe port is a pipe 21 which pipe .is connected to the brake cylinder B.A valve 23 snugly fits within the bore of the chamber 4, and isconnected to the valve 6 by a stem 24. The valve 23 normally closes theport 22 so that the air in the brake cylinder cannot escape through thepipe 21 when the air is caused to be introduced into. the brake cylinderfor applying the brakes. When the brakes are released, the valves 23 and6 will be caused to move upward by the air entering the valve chamber 4through the pipe 19, and as the valve 23 moves upward it opens the ports22 and 25 thereby permitting the air from the brake cylinder to enterthe chamber 1 through the pipe 21 and port 22, the air then passing tothe atmosphere through the port 25. This valve 23 and the connectionwhich the chamber 4; has with the brake cylinder is very important forthe reason that with the air being admitted to the auxiliary reservoirthrough the pipe 19 and valve casing as well as through the triplevalve, a supply of air would be admitted to the reservoir which wouldprevent the valve from acting suiliciently to allow the escape of theair from the brake cylinder, but with this additional connection of thepipe 21 with the valvechamber 4 the air can be discharged from the brakecylinder without any possibility of the brakes setting due to I the factthat the auxiliary reservoir is being recharged more rapidly than ispossible with the ordinary method of passing the air through thetriplevalvea With this apparatus, the auxiliary reservoir can bere-supplied with air more rapidly than in the present system in vogue ofintroducing the air through the triple valve and by providing meanswhereby the auxiliary reservoir can be recharged more rapidly, thebrakes can be used again in less time than in the present method.Several minutes are required for the recharging of the auxiliaryreservoir with the present method in vogue, and if for any reason itisnecessary to reset the brakes there is not enough air in the reservoirto cause the brakes to be applied. and it is for this reason ervoirwould receive its supply of air before all of the air could bedischarged from the brake cylinder, audit is to overcome this diflicultythat I have provided a connection between the brake cylinder and my mainvalve chamber so that the air from the brake cylinder can be dischargedthrough the main valve chamber to the atmosphere during the time theauxiliary reservoir is being recharged as the valve 23 will open theports 22 and 25 as soon as the air is admitted for the recharging of theauxiliary reservoir.

Another feature of this invention is in the provision of the valves 6and 11. If for any reason one of the valves should fail to become seatedto prevent the escape of air from the auxiliary reservoir, the otherwould act. The valve 11 will act first and when the passage 16 isclosed, the air from. the

reservoir will pass thereover and force the valve 6 down and insure thesetting of the valve as the air will fiow directly over the top of valve6 and cause it to become seated. The valve 6 will, under ordinaryconditions, seat itself the same as the valve 11, but to overcome anypossibility or failure, of the valve 6 to work, I have provided thevalve 11 to insure the closing of the port and prevent the escape of airfrom the auxiliary reservoir.

A plug 26 is connected to the bottom of the chamber 5 whereby thechamber can be cleaned of any foreign matter which may enter the chamberand I have provided plugs 27 and 28 in the heads of the cham bers 5 and41 respectively whereby oil can be introduced for lubricating the valvestems 8 and 13.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent isi 1. The combination with an auxiliary re's-,

ervoir and an air supply means of an air brake system, of a valve casingconsisting of valve chambers in communication with each other byconduits, means connecting one of said chambers to the auxiliaryreservoir and means. connecting the other chamber to the air supplymeans, a valve in each chamber adapted to be raised upon the charging ofthe auxiliary reservoir, said valves adapted to be seated when anequalizing pressure is reached between the auxiliary reservoir and theair supplying means, one of said passages being in communication withthe auxiliary reservoir causing the air of the auxiliary reservoir toact upon 'means of an air brake system,

2 the brakes,

roeaaaa one of said valves to cause said valve to be seated.

- 2. The combination with a brake cylinder, an auxiliary reservoir, andan air supply- 5 ing means ofan air brake system, of a valve casingconnected to theauxiliary reservoir and said air supplying means for therecharging of the auxiliary reservoir means,

connected to the brake cylinder and said valve casing for, conductingthe air from the brake. cylinder upon the release of the brakes, andmeans controlled by the air passing through the valve casing forgoverning' the, passage of air from the brake cylin- 1.5 'der to thevalve casing.

3. The combination with a brake cylinder, an auxiliary reservoir, and anair supplying of a valve casing connected to the auxiliary reservoir 2and; said air supplyingmeans for the repasses through the valve casingtothe auiziliar'y reservoirto allow the air from the bralgecflinderto bedischarged to the atmosphere.

tl'opiel of this patent may be ob tained for live cents each, byaddressing the Commissioner Washington, D. G.

4c. The combination With' an auxiliary reservoir, brake cylinder and airsupply pipe, and a triple valve connected to and in communication withthe auxiliary reservoir, a pipe connecting the triple, valve With thebrake cylinder and a pipe connecting the air supply pipe with the'triplevalve, 0f-a valve casing in communication with the auxiliaryreservoirand air supply pipe, valves in the casing for controlling theadmission of airto the reservoir and means connecting the brake cylinderwith the valve casing acting in connection With the triple valve fordischarging the air from the brake cylinder to release the brakes.

5. The combination with a brake cylinder, auxiliary reservoir and airsupply means, of a. valve casing, means connecting the valve casing withthe auxiliary reservoir, a valve in the casing for controlling the supply of airto the reservoir, means connecting the, valve casing to thebrake cylinder for conducting the air from the brake cylinder upon thereleasing of the brakes to the at- I mosphere and a valve connected tosaid first named valve for controlhng the discharge of the air from thebrakecylinder.
